Male sterile "lines" are being made carrying either Ne ss or Nets in homozygous condition. The "lines" will be used to determine the necrosis genotype of wheat varieties and at the same time to trace genes restoring fertility in cytoplasmic sterile "lines" . It is suggested that hybrid necrosis cou

New data about the geographical distribution of necrosis genes support the previous conclusion, viz. the Old World can be divided by a rough line running through the Mediterranean and Black Sea countries to Lake Baikal and from these to northern Japan. The Ne,-area lies south and east and the Ne, ar

Hybrid necrosis in wheat is a barrier to gene transfer in wheat breeding practice. It is based on two complementary genes, Ne1 and Ne2. Recovery mutants (Re1, Re2 and Re3) which can grow to maturity were recovered from immature embryo cultures of necrotic hybrids between T. aestivum and T. durum. Cy

The results of a cytological study of hybrid necrosis in wheat are presented. Two types of necrosizing of the leaves have been found viz. necrosis via dull green discoloration, and necrosis via a yellow intermediate colour. In the first case the conglomeration of the cell contents starts when the si
